Nationals honor Memorial Day with military, a united Presidents Race and more

The Nationals opened up an Interleague series against the Orioles on Memorial Day, and along with honoring those who have served our country, the team recognized members of T.A.P.S. (Tragedy Assistance Program for Survivors) and held a unique Presidents Race. Here's a photo/video rundown from the afternoon:
